Facebook is to roll out a major set of changes to its News Feed which are designed to load content that is more relevant to each individual user.

Described by Facebook's engineering manager for News Feed Ranking as a "personalised newspaper", the new feed features three major changes, which have already been tested with a small number of the site's members.

The first change is called 'Story Bumping' and is based around the way in which users view their Facebook news feeds. The idea behind story bumping is that it stops members of the site from missing relevant stories and skips content which they might not find interesting.

In future, when users load up the News Feed, it will populate with stories that are "new to you". This means stories users may have previously missed - regardless of the time they were posted on Facebook - will be pushed to the top of the News Feed.

Facebook uses a complicated algorithm to calculate how stories are relevant to its users based on criteria such as number of likes, comments and how close the person is to the user.

The result of the Story Bump feature should be that more relevant Facebook posts appear higher up in news feeds. Facebook said that in testing, this has resulted in an increase in interactions with stories. Story Bump should now be live on web-based versions of Facebook.

The second change to be rolled out relating to the way Facebook organises the News Feed is based around the last 50 interactions a person had on the site.

It means that people a user has had recent interactions with will also be used as part of the ranking criteria.

Finally, there is what Facebook calls 'chronological by actor', which is a new way that Facebook will collate posts about specific events together and put them in order.

If, for example, a friend posts about a particular event such as a football match, then multiple posts relating to that single event will appear chronologically in a user's news feed and should be exempt from the Story Bump function.

Facebook is still working on the 'chronological by actor' function, which will be rolled out universally soon.
